ABSTRACT

A novel garden bean cultivar, designated H37112, is disclosed. The invention relates to the seeds of garden bean cultivar H37112, to the plants of garden bean line H37112, and to methods for producing a bean plant by crossing the cultivar H37112 with itself or another bean line. The invention further relates to methods for producing a bean plant containing in its genetic material one or more transgenes, and to the transgenic plants produced by that method, and to methods for producing other garden bean lines derived from the cultivar H37112.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive garden bean cultivar (Phaseolus vulgaris), designated H37112. All publications cited in this application are herein incorporated by reference.

There are numerous steps in the development of any novel, desirable plant germplasm. Plant breeding begins with the analysis and definition of problems and weaknesses of the current germplasm, the establishment of program goals, and the definition of specific breeding objectives. The next step is selection of germplasm that possesses the traits to meet the program goals. The goal is to combine in a single variety an improved combination of desirable traits from the parental germplasm.

In beans, these important traits may include fresh pod yield, higher seed yield, resistance to diseases and insects, better stems and roots, tolerance to drought and heat, and better agronomic quality. With mechanical harvesting of many crops, uniformity of the plants' characteristics, such as germination and stand establishment, growth rate, maturity, and plant height, is important.

Choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of cultivar used commercially (e.g., F₁ hybrid cultivar, pureline cultivar, etc.). For highly heritable traits, a choice of superior individual plants evaluated at a single location will be effective, whereas for traits with low heritability, selection should be based on mean values obtained from replicated evaluations of families of related plants. Popular selection methods commonly include pedigree selection, modified pedigree selection, mass selection, recurrent selection, and backcross breeding.

The complexity of inheritance influences choice of the breeding method. Backcross breeding is used to transfer one or a few favorable genes for a highly heritable trait into a desirable cultivar. This approach has been used extensively for breeding disease-resistant cultivars. Nevertheless, it is also suitable for the adjustment and selection of morphological character, color characteristics, and simply inherited quantitative characters. Various recurrent selection techniques are used to improve quantitatively inherited traits controlled by numerous genes. The use of recurrent selection in self-pollinating crops depends on the ease of pollination, the frequency of successful hybrids from each pollination, and the number of hybrid offspring from each successful cross.

Each breeding program should include a periodic, objective evaluation of the efficiency of the breeding procedure. Evaluation criteria vary depending on the goal and objectives, but should include gain from selection per year based on comparisons to an appropriate standard, overall value of the advanced breeding lines, and number of successful cultivars produced per unit of input (e.g., per year, per dollar expended, etc.).

Promising advanced breeding lines are thoroughly tested and compared to appropriate standards in environments representative of the commercial target area(s) for three or more years. The best lines are candidates for new commercial cultivars. Those still deficient in a few traits may be used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing and distribution, usually take from eight to twelve years from the time the first cross is made. Therefore, development of new cultivars is a time-consuming process that requires precise forward planning, efficient use of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that are genetically superior, because for most traits the true genotypic value is masked by other confounding plant traits or environmental factors. One method of identifying a superior plant is to observe its performance relative to other experimental plants and to a widely grown standard cultivar. If a single observation is inconclusive, replicated observations provide a better estimate of its genetic worth.

The goal of garden bean plant breeding is to develop new, unique, and superior garden bean cultivars. The breeder initially selects and crosses two or more parental lines, followed by repeated selfing and selection, producing many new genetic combinations. The breeder can theoretically generate billions of different genetic combinations via crossing, selfing, and mutations.

Each year, the plant breeder selects the germplasm to advance to the next generation. This germplasm is grown under unique and different geographical, climatic, and soil conditions, and further selections are then made during and at the end of the growing season. The cultivars that are developed are unpredictable. This unpredictability is because the breeder's selection occurs in unique environments with no control at the DNA level (using conventional breeding procedures), and with millions of different possible genetic combinations being generated. A breeder of ordinary skill in the art cannot predict the final resulting lines he develops, except possibly in a very gross and general fashion. This unpredictability results in the expenditure of large amounts of research monies to develop superior new garden bean cultivars.

The development of new garden bean cultivars requires the development and selection of garden bean varieties, the crossing of these varieties, and the evaluation of the crosses.

Pedigree breeding and recurrent selection breeding methods are used to develop cultivars from breeding populations. Breeding programs combine desirable traits from two or more cultivars or various broad-based sources into breeding pools from which cultivars are developed by selfing and selection of desired phenotypes.

Pedigree breeding is used commonly for the improvement of self-pollinating crops or inbred lines of cross-pollinating crops. Two parents that possess favorable, complementary traits are crossed to produce an F₁. An F₂ population is produced by selfing one or several F₁s or by intercrossing two F₁s (sib mating). Selection of the best individuals may begin in the F₂ population; then, beginning in the F₃, the best individuals in the best families are selected. Replicated testing of families, or hybrid combinations involving individuals of these families, often follows in the F₄ generation to improve the effectiveness of selection for traits with low heritability. At an advanced stage of inbreeding (i.e., F₆ and F₇), the best lines or mixtures of phenotypically similar lines are tested for potential release as new cultivars.

Mass and recurrent selections can be used to improve populations of either self- or cross-pollinating crops. A genetically variable population of heterozygous individuals is either identified, or created, by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simply inherited, highly heritable trait into a desirable homozygous cultivar or inbred line which is the recurrent parent. The source of the trait to be transferred is called the donor parent. The resulting plant is expected to have the attributes of the recurrent parent (e.g., cultivar) and the desirable trait transferred from the donor parent. After the initial cross, individuals possessing the phenotype of the donor parent are selected and repeatedly crossed (backcrossed) to the recurrent parent.

The single-seed descent procedure in the strict sense refers to planting a segregating population, harvesting a sample of one seed per plant, and using the one-seed sample to plant the next generation. When the population has been advanced from the F₂ to the desired level of inbreeding, the plants from which lines are derived will each trace to different F₂ individuals. The number of plants in a population declines each generation due to failure of some seeds to germinate or some plants to produce at least one seed. As a result, not all of the F₂ plants originally sampled in the population will be represented by a progeny when generation advance is completed.

In a multiple-seed procedure, garden bean breeders commonly harvest one or more pods from each plant in a population and thresh them together to form a bulk. Part of the bulk is used to plant the next generation and part is put in reserve. The procedure has been referred to as modified single-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. It is considerably faster to thresh pods with a machine than to remove one seed from each by hand for the single-seed procedure. The multiple-seed procedure also makes it possible to plant the same number of seeds of a population each generation of inbreeding. Enough seeds are harvested to make up for those plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used for different traits and crops can be found in one of several reference books (e.g., Principles of Plant Breeding, John Wiley and Son, pp. 115-161, 1960; Allard, 1960; Fehr, 1987).

Proper testing should detect any major faults and establish the level of superiority or improvement over current cultivars. In addition to showing superior performance, there must be a demand for a new cultivar that is compatible with industry standards or which creates a new market. The introduction of a new cultivar will incur additional costs to the seed producer, the grower, processor and consumer for special advertising and marketing, altered seed and commercial production practices, and new product utilization. The testing preceding release of a new cultivar should take into consideration research and development costs as well as technical superiority of the final cultivar. For seed-propagated cultivars, it must be feasible to produce seed easily and economically.

Garden bean, Phaseolus vulgaris L., is an important and valuable vegetable crop. Thus, a continuing goal of garden bean plant breeders is to develop stable, high yielding garden bean cultivars that are agronomically sound. The reasons for this goal are obviously to maximize the amount of yield produced on the land. To accomplish this goal, the garden bean breeder must select and develop garden bean plants that have traits that result in superior cultivars.

The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification.

SUMMARY OF THE INVENTION

The following embodiments and aspects thereof are described in conjunction with systems, tools and methods which are meant to be exemplary, not limiting in scope. In various embodiments, one or more of the above-described problems have been reduced or eliminated, while other embodiments are directed to other improvements.

According to the invention, there is provided a novel garden bean cultivar, designated H37112. This invention thus relates to the seeds of garden bean cultivar H37112, to the plants or part(s) thereof of garden bean cultivar H37112, to plants or part(s) thereof having all the phenotypic and morphological characteristics of garden bean cultivar H37112, and to plants or part(s) thereof having the phenotypic and morphological characteristics of garden bean cultivar H37112 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions. Plant parts of the garden bean cultivar of the present invention are also provided such as, i.e., pollen obtained from the plant cultivar and an ovule obtained from the plant cultivar.

In another aspect, the present invention provides regenerable cells for use in tissue culture of bean cultivar H37112. The tissue culture will preferably be capable of regenerating plants having the physiological and morphological characteristics of bean cultivar H37112. Preferably, the cells of such tissue culture will be embryos, meristematic cells, seeds, callus, pollen, leaves, anthers, pistils, roots, root tips, pods, flowers, and stems. Protoplasts produced from such tissue culture are also included in the present invention. The bean plants regenerated from the tissue culture are also part of the invention.

Also included in the invention are methods for producing a bean plant produced by crossing bean cultivar H37112 with itself or another bean cultivar. When crossed with itself, i.e., when crossed with another bean cultivar H37112 plant or self-pollinated, bean cultivar H37112 will be conserved. When crossed with another, different bean plant, an F₁ hybrid seed is produced. F₁ hybrid seeds and plants produced by growing said hybrid seeds are included in the present invention. A method for producing an F₁ hybrid bean seed comprising crossing a bean cultivar H37112 plant with a different bean plant and harvesting the resultant hybrid bean seed are also part of the invention. The hybrid bean seed produced by the method comprising crossing a bean cultivar H37112 plant with a different bean plant and harvesting the resultant hybrid bean seed, are included in the invention, as are the hybrid bean plant or part(s) thereof, and seeds produced by growing said hybrid bean seed.

In another aspect, the present invention provides for transformed H37112 bean cultivar plants, or part(s) thereof that have been transformed, so that its genetic material contains one or more transgenes, preferably operably linked to one or more regulatory elements. Also, the invention provides methods for producing a bean plant containing in its genetic material one or more transgenes, preferably operably linked to one or more regulatory elements, by crossing transformed H37112 bean cultivar plants with either a second plant of another bean cultivar, or a nontransformed H37112 bean cultivar, so that the genetic material of the progeny that results from the cross contains the transgene(s), preferably operably linked to one or more regulatory elements. The invention also provides methods for producing a bean plant that contains in its genetic material one or more transgene(s), wherein the method comprises crossing the cultivar H37112 with a second bean cultivar of another bean cultivar which contains one or more transgene(s) operably linked to one or more regulatory element(s) so that the genetic material of the progeny that results from the cross contains the transgene(s) operably linked to one or more regulatory element(s). Transgenic bean cultivars, or part(s) thereof produced by the methods are in the scope of the present invention.

More specifically, the invention comprises methods for producing a male sterile bean plant, an herbicide resistant bean plant, an insect resistant bean plant, a disease resistant bean plant, a water stress tolerant bean plant, a heat stress tolerant bean plant, and a bean plant with improved shelf-life. Said methods comprise transforming a bean cultivar H37112 plant with a nucleic acid molecule that confers male sterility, herbicide resistance, insect resistance, disease resistance, water stress tolerance, heat stress tolerance, or improved shelf life, respectively. The transformed bean plants, or part(s) thereof, obtained from the provided methods, including a male sterile bean plant, an herbicide resistant bean plant, an insect resistant bean plant, a disease resistant bean plant, a bean plant tolerant to water stress, a bean plant tolerant to heat stress, or a bean plant with improved shelf-life are included in the present invention. For the present invention and the skilled artisan, disease is understood to be fungal diseases, viral diseases, bacterial diseases, or other plant pathogenic diseases, and a disease resistant plant will encompass a plant resistant to fungal, viral, bacterial, and other plant pathogens.

In another aspect, the present invention provides for methods of introducing one or more desired trait(s) into bean cultivar H37112 and plants obtained from such methods. The desired trait(s) may be, but not exclusively, a single gene, preferably a dominant, but also a recessive allele. Preferably, the transferred gene or genes will confer such traits as male sterility, herbicide resistance, insect resistance, resistance to bacterial, fungal, or viral disease, increased leaf number, improved shelf-life, and tolerance to water stress or heat stress. The gene or genes may be naturally occurring gene(s) or transgene(s) introduced through genetic engineering techniques. The method for introducing the desired trait(s) is preferably a backcrossing process making use of a series of backcrosses to bean cultivar H37112 during which the desired trait(s) is maintained by selection.

When using a transgene, the trait is generally not incorporated into each newly developed line/cultivar such as bean cultivar H37112 by direct transformation. Rather, the more typical method used by breeders of ordinary skill in the art to incorporate the transgene is to take a line already carrying the transgene and to use such line as a donor line to transfer the transgene into the newly developed line. The same would apply for a naturally occurring trait. The backcross breeding process comprises the following steps: (a) crossing bean cultivar H37112 plants with plants of another cultivar that comprise the desired trait(s); (b) selecting the F₁ progeny plants that have the desired trait(s); (c) crossing the selected F₁ progeny plants with bean cultivar H37112 plants to produce backcross progeny plants; (d) selecting for backcross progeny plants that have the desired trait(s) and physiological and morphological characteristics of bean cultivar H37112 to produce selected backcross progeny plants; and (e) repeating steps (c) and (d) one, two, three, four, five, six, seven, eight, nine, or more times in succession to produce selected, second, third, fourth, fifth, sixth, seventh, eighth, ninth, or higher backcross progeny plants that comprise the desired trait(s) and the physiological and morphological characteristics of bean cultivar H37112 as determined in Table 1 at a 5% significance level when grown in the same environmental conditions. The bean plants produced by the methods are also part of the invention. Backcrossing breeding methods, well known for a man skilled in the art of plant breeding, will be further developed in subsequent parts of the specification.

In a preferred embodiment, the present invention provides methods for increasing and producing bean cultivar H37112 seed, whether by crossing a first parent bean cultivar plant with a second parent bean cultivar plant and harvesting the resultant bean seed, wherein both said first and second parent bean cultivar plants are the bean cultivar H37112 or by planting a bean seed of the bean cultivar H37112, growing a bean cultivar H37112 plant from said seed, controlling a self pollination of the plant where the pollen produced by a grown bean cultivar H37112 plant pollinates the ovules produced by the very same bean cultivar H37112 grown plant, and harvesting the resultant seed.

The invention further provides methods for developing bean cultivars in a bean breeding program using plant breeding techniques including recurrent selection, backcrossing, pedigree breeding, molecular markers (Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats (SSRs), which are also referred to as Microsatellites, etc.) enhanced selection, genetic marker enhanced selection, and transformation. Seeds, bean plants, and part(s) thereof produced by such breeding methods are also part of the invention.

In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by study of the following descriptions.

DETAILED DESCRIPTION OF THE INVENTION

Garden bean cultivar H37112 has superior characteristics and was developed from an initial cross that was made in San Juan Bautista (SJB), Calif., in a greenhouse, in the spring of 2002. The cross was between two proprietary garden bean lines under stake numbers M7017 (female) and M7043 (male). The F₁ generation was harvested in September 2002 in SJB, Calif. in plot 8X0162. The F₂ selection was made February 2003 at research grounds near Los Mochis, Mexico in plot 9N0768. The F₃ selection was made in July 2003 at research grounds near Coloma, Wis. in plot 9Y0986. The F₄ selection was made in February 2004 at research grounds near Los Mochis, Mexico in plot M41255. The F₅ selection was made in July 2004 at research grounds near Coloma, Wis. in plot H409952. The F₆ selection was made in March 2005 at research grounds near Immokalee, Fla. in plot F500024. The F₇ generation was bulked in September 2005 at research grounds in SJB, Calif. in plot C510192. The F₈ generation was bulked in September 2006 at research grounds in SJB, Calif. in plot C604238. The F₉ generation was bulked in March 2007 at research grounds near Los Mochis, Mexico in plot M74201. The line was designated H37112.

Garden bean cultivar H37112 is similar to garden bean cultivar ‘Caprice’. While similar to garden bean cultivar ‘Caprice’, there are significant differences including garden bean cultivar H37112 has pods that are smaller in diameter than garden bean cultivar ‘Caprice.’ In addition, garden bean cultivar H37112 is resistant to Beet Curly Top Virus and Uromyces appendiculatus races 38, 53 and 72, while garden bean cultivar ‘Caprice’ is susceptible. In addition, garden bean cultivar H37112 reaches maturity three days earlier than ‘Caprice.’

Garden bean cultivar H37112 is a 53-day, medium-maturity bean with uniform medium-dark green pods on an upright plant structure (habit). The pods are straight and smooth and are borne in the middle of the plant. The majority of the pods are in the 3-4 sieves range. The leaves are medium in size with a medium-dark green, semi-glossy color. Garden bean cultivar H37112 is a determinate plant and is resistant to Bean Common Mosaic Virus (BCMV I-gene), Beet Curly Top Virus, Uromyces appendiculatus races 38, 53 and 72, and Pseudomonas syringae pv. phaseolicola (Halo Blight).

Some of the selection criteria used for various generations include: pod appearance and length, bean yield, pod set height, emergence, maturity, plant architecture, habit and height, seed yield and quality and disease resistance.

Bean Common Mosaic Virus resistance is a desired trait for a bean variety. The disease occurs worldwide causing low quality of the harvest product and losses from 80% to 100% by reduction of yield. It is mostly transmitted by aphids during the growing season, but can also be spread by pollen or mechanically. The leaves develop mosaic patterns in which irregular light and dark green patches are intermixed. Malformation and yellow dots may also be produced, often causing growth reduction. The plant may be dwarfed and pod and seed yield reduced. Severe necrosis may occur and the plant may die if infected while young. Systemic necrosis, in which the roots and shoots become blackened, appears in cultivars having a dominant resistance gene (hypersensitive resistance mechanism). The systemic necrosis may spread to higher leaves without killing them or may be concentrated in the vascular parts of the stem, eventually leading to the death of all or part of the plant. When infection occurs late in plant development, parts of the plant may die and many pods may show brown discoloration in the pod wall and pod suture as a result of vascular necrosis.

Garden bean cultivar H37112 has shown uniformity and stability for the traits, as described in the following Variety Description Information. It has been self-pollinated a sufficient number of generations with careful attention to uniformity of plant type. The cultivar has been increased with continued observation for uniformity. No variant traits have been observed or are expected in garden bean cultivar H37112.

Garden bean cultivar H37112 has the following morphologic and other characteristics (based primarily on data collected at Immokalee, Fla., Crossville, Tenn., and Sun Prairie, Wis.).

FURTHER EMBODIMENTS OF THE INVENTION

This invention also is directed to methods for producing a garden plant by crossing a first parent bean plant with a second parent bean plant wherein either the first or second parent bean plant is a bean plant of the line H37112. Further, both first and second parent bean plants can come from cultivar H37112. When self pollinated, or crossed with another bean cultivar H37112 plant, the bean cultivar H37112 will be stable, while when crossed with another, different bean cultivar plant, an F₁ hybrid seed is produced.

Still further, this invention also is directed to methods for producing an H37112-derived bean plant by crossing cultivar H37112 with a second bean plant and growing the progeny seed, and repeating the crossing and growing steps with the cultivar H37112-derived plant from 0 to 7 times. Thus, any such methods using the cultivar H37112 are part of this invention: selfing, backcrosses, hybrid production, crosses to populations, and the like. All plants produced using cultivar H37112 as a parent are within the scope of this invention, including plants derived from cultivar H37112. Advantageously, the cultivar is used in crosses with other, different cultivars to produce first generation (F₁) bean seeds and plants with superior characteristics.

As used herein, the term “plant” includes plant cells, plant protoplasts, plant cell tissue cultures from which garden bean plants can be regenerated, plant calli, plant clumps and plant cells that are intact in plants or parts of plants, such as embryos, pollen, ovules, flowers, seeds, pods, stems, roots, anthers, pistils, root tips, leaves, and the like.

As is well known in the art, tissue culture of garden bean can be used for the in vitro regeneration of a garden bean plant.

It is clear from the literature that the state of the art is such that these methods of obtaining plants are routinely used and have a very high rate of success. Thus, another aspect of this invention is to provide cells which upon growth and differentiation produce bean plants having the physiological and morphological characteristics of garden bean cultivar H37112.

As used herein, the term “tissue culture” indicates a composition comprising isolated cells of the same or a different type or a collection of such cells organized into parts of a plant. Exemplary types of tissue cultures are protoplasts, calli, plant clumps, and plant cells that can generate tissue culture that are intact in plants or parts of plants, such as embryos, pollen, flowers, seeds, pods, leaves, stems, roots, root tips, anthers, pistils, and the like. Means for preparing and maintaining plant tissue culture are well known in the art. By way of example, a tissue culture comprising organs has been used to produce regenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234, and 5,977,445 describe certain techniques, the disclosures of which are incorporated herein by reference.

With the advent of molecular biological techniques that have allowed the isolation and characterization of genes that encode specific protein products, scientists in the field of plant biology developed a strong interest in engineering the genome of plants to contain and express foreign genes, or additional, or modified versions of native, or endogenous, genes (perhaps driven by different promoters) in order to alter the traits of a plant in a specific manner. Such foreign additional and/or modified genes are referred to herein collectively as “transgenes.” Over the last fifteen to twenty years, several methods for producing transgenic plants have been developed and the present invention, in particular embodiments, also relates to transformed versions of the claimed variety or line.

Plant transformation involves the construction of an expression vector which will function in plant cells. Such a vector comprises DNA comprising a gene under control of, or operatively linked to, a regulatory element (for example, a promoter). The expression vector may contain one or more such operably linked gene/regulatory element combinations. The vector(s) may be in the form of a plasmid and can be used alone or in combination with other plasmids to provide transformed garden bean plants using transformation methods as described below to incorporate transgenes into the genetic material of the garden bean plant(s).

Expression Vectors for Garden Bean Transformation: Marker Genes

Expression vectors include at least one genetic marker operably linked to a regulatory element (a promoter, for example) that allows transformed cells containing the marker to be either recovered by negative selection, i.e., inhibiting growth of cells that do not contain the selectable marker gene, or by positive selection, i.e., screening for the product encoded by the genetic marker. Many commonly used selectable marker genes for plant transformation are well known in the transformation arts, and include, for example, genes that code for enzymes that metabolically detoxify a selective chemical agent which may be an antibiotic or an herbicide, or genes that encode an altered target which is insensitive to the inhibitor. A few positive selection methods are also known in the art.

One commonly used selectable marker gene for plant transformation is the neomycin phosphotransferase II (nptII) gene which, when under the control of plant regulatory signals, confers resistance to kanamycin. Fraley, et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983). Another commonly used selectable marker gene is the hygromycin phosphotransferase gene which confers resistance to the antibiotic hygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that confer resistance to antibiotics include gentamycin acetyl transferase, streptomycin phosphotransferase and aminoglycoside-3′-adenyl transferase, the bleomycin resistance determinant (Hayford, et al., Plant Physiol., 86:1216 (1988); Jones, et al., Mol. Gen. Genet., 210:86 (1987); Svab, et al., Plant Mol. Biol., 14:197 (1990); Hille, et al., Plant Mol. Biol., 7:171 (1986)). Other selectable marker genes confer resistance to herbicides such as glyphosate, glufosinate or bromoxynil (Comai, et al., Nature, 317:741-744 (1985); Gordon-Kamm, et al., Plant Cell, 2:603-618 (1990); and Stalker, et al., Science, 242:419-423 (1988)).

Other selectable marker genes for plant transformation are not of bacterial origin. These genes include, for example, mouse dihydrofolate reductase, plant 5-enolpyruvylshikimate-3-phosphate synthase and plant acetolactate synthase. Eichholtz, et al., Somatic Cell Mol. Genet., 13:67 (1987); Shah, et al., Science, 233:478 (1986); Charest, et al., Plant Cell Rep., 8:643 (1990).

Another class of marker genes for plant transformation requires screening of presumptively transformed plant cells rather than direct genetic selection of transformed cells for resistance to a toxic substance such as an antibiotic. These genes are particularly useful to quantify or visualize the spatial pattern of expression of a gene in specific tissues and are frequently referred to as reporter genes because they can be fused to a gene or gene regulatory sequence for the investigation of gene expression. Commonly used genes for screening presumptively transformed cells include β-glucuronidase (GUS), β-galactosidase, luciferase, and chloramphenicol acetyltransferase (Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri, et al., EMBO J., 8:343 (1989); Koncz, et al., Proc. Natl. Acad. Sci. USA, 84:131 (1987); DeBlock, et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not require destruction of plant tissue are available. However, these in vivo methods for visualizing GUS activity have not proven useful for recovery of transformed cells because of low sensitivity, high fluorescent backgrounds and limitations associated with the use of luciferase genes as selectable markers.

A gene encoding Green Fluorescent Protein (GFP) has been utilized as a marker for gene expression in prokaryotic and eukaryotic cells (Chalfie, et al., Science, 263:802 (1994)). GFP and mutants of GFP may be used as screenable markers.

Expression Vectors for Garden Bean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotide sequence comprising a regulatory element, for example, a promoter. Several types of promoters are well known in the transformation arts as are other regulatory elements that can be used alone or in combination with promoters.

As used herein, “promoter” includes reference to a region of DNA upstream from the start of transcription and involved in recognition and binding of RNA polymerase and other proteins to initiate transcription. A “plant promoter” is a promoter capable of initiating transcription in plant cells. Examples of promoters under developmental control include promoters that preferentially initiate transcription in certain tissues, such as leaves, roots, seeds, fibers, xylem vessels, tracheids, or sclerenchyma. Such promoters are referred to as “tissue-preferred.” Promoters that initiate transcription only in a certain tissue are referred to as “tissue-specific.” A “cell-type” specific promoter primarily drives expression in certain cell types in one or more organs, for example, vascular cells in roots or leaves. An “inducible” promoter is a promoter which is under environmental control. Examples of environmental conditions that may effect transcription by inducible promoters include anaerobic conditions or the presence of light. Tissue-specific, tissue-preferred, cell-type specific, and inducible promoters constitute the class of “non-constitutive” promoters. A “constitutive” promoter is a promoter that is active under most environmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to a gene for expression in garden bean. Optionally, the inducible promoter is operably linked to a nucleotide sequence encoding a signal sequence which is operably linked to a gene for expression in garden bean. With an inducible promoter the rate of transcription increases in response to an inducing agent.

Any inducible promoter can be used in the instant invention. See, Ward, et al., Plant Mol. Biol., 22:361-366 (1993). Exemplary inducible promoters include, but are not limited to, that from the ACEI system which responds to copper (Mett, et al., Proc. Natl. Acad. Sci. USA, 90:4567-4571 (1993)); In2 gene from maize which responds to benzenesulfonamide herbicide safeners (Gatz, et al., Mol. Gen. Genetics, 243:32-38 (1994)); or Tet repressor from Tn10 (Gatz, et al., Mol. Gen. Genetics, 227:229-237 (1991)). A particularly preferred inducible promoter is a promoter that responds to an inducing agent to which plants do not normally respond. An exemplary inducible promoter is the inducible promoter from a steroid hormone gene, the transcriptional activity of which is induced by a glucocorticosteroid hormone (Schena, et al., Proc. Natl. Acad. Sci. USA, 88:0421 (1991)).

B. Constitutive Promoters—A constitutive promoter is operably linked to a gene for expression in garden bean or the constitutive promoter is operably linked to a nucleotide sequence encoding a signal sequence which is operably linked to a gene for expression in garden bean.

Many different constitutive promoters can be utilized in the instant invention. Exemplary constitutive promoters include, but are not limited to, the promoters from plant viruses such as the 35S promoter from CaMV (Odell, et al., Nature, 313:810-812 (1985)) and the promoters from such genes as rice actin (McElroy, et al., Plant Cell, 2:163-171 (1990)); ubiquitin (Christensen, et al., Plant Mol. Biol., 12:619-632 (1989) and Christensen, et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU (Last, et al., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten, et al., EMBO J., 3:2723-2730 (1984)) and maize H3 histone (Lepetit, et al., Mol. Gen. Genetics, 231:276-285 (1992) and Atanassova, et al., Plant Journal, 2 (3):291-300 (1992)). The ALS promoter, Xba1/Nco1 fragment 5′ to the Brassica napus ALS3 structural gene (or a nucleotide sequence similarity to said Xba1/Nco1 fragment), represents a particularly useful constitutive promoter. See PCT Application WO 96/30530.

C. Tissue-Specific or Tissue-Preferred Promoters—A tissue-specific promoter is operably linked to a gene for expression in garden bean. Optionally, the tissue-specific promoter is operably linked to a nucleotide sequence encoding a signal sequence which is operably linked to a gene for expression in garden bean. Plants transformed with a gene of interest operably linked to a tissue-specific promoter produce the protein product of the transgene exclusively, or preferentially, in a specific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in the instant invention. Exemplary tissue-specific or tissue-preferred promoters include, but are not limited to, a root-preferred promoter such as that from the phaseolin gene (Murai, et al., Science, 23:476-482 (1983) and Sengupta-Gopalan, et al., Proc. Natl. Acad. Sci. USA, 82:3320-3324 (1985)); a leaf-specific and light-induced promoter such as that from cab or rubisco (Simpson, et al., EMBO J., 4(11):2723-2729 (1985) and Timko, et al., Nature, 318:579-582 (1985)); an anther-specific promoter such as that from LAT52 (Twell, et al., Mol. Gen. Genetics, 217:240-245 (1989)); a pollen-specific promoter such as that from Zm13 or a microspore-preferred promoter such as that from apg (Twell, et al., Sex. Plant Reprod., 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of protein produced by transgenes to a subcellular compartment such as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall, or mitochondrion or for secretion into the apoplast, is accomplished by means of operably linking the nucleotide sequence encoding a signal sequence to the 5′ and/or 3′ region of a gene encoding the protein of interest. Targeting sequences at the 5′ and/or 3′ end of the structural gene may determine during protein synthesis and processing where the encoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either an intracellular organelle or subcellular compartment or for secretion to the apoplast. Many signal sequences are known in the art. See, for example, Becker, et al., Plant Mol. Biol., 20:49 (1992); Knox, C., et al., “Structure and Organization of Two Divergent Alpha-Amylase Genes from Barley,” Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., Plant Physiol., 91:124-129 (1989); Fontes, et al., Plant Cell, 3:483-496 (1991); Matsuoka, et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould, et al., J. Cell. Biol., 108:1657 (1989); Creissen, et al., Plant J., 2:129 (1991); Kalderon, et al., Cell, 39:499-509 (1984); Steifel, et al., “Expression of a maize cell wall hydroxyproline-rich glycoprotein gene in early leaf and root vascular differentiation,” Plant Cell, 2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreign protein can be produced in commercial quantities. Thus, techniques for the selection and propagation of transformed plants, which are well understood in the art, yield a plurality of transgenic plants which are harvested in a conventional manner, and a foreign protein then can be extracted from a tissue of interest or from total biomass. Protein extraction from plant biomass can be accomplished by known methods which are discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6 (1981).

According to a preferred embodiment, the transgenic plant provided for commercial production of foreign protein is a garden bean plant. In another preferred embodiment, the biomass of interest is seed. For the relatively small number of transgenic plants that show higher levels of expression, a genetic map can be generated, primarily via conventional RFLP, PCR, and SSR analysis, which identifies the approximate chromosomal location of the integrated DNA molecule. For exemplary methodologies in this regard, see Methods in Plant Molecular Biology and Biotechnology, Glick and Thompson Eds., CRC Press, Inc., Boca Raton, 269:284 (1993). Map information concerning chromosomal location is useful for proprietary protection of a subject transgenic plant. If unauthorized propagation is undertaken and crosses made with other germplasm, the map of the integration region can be compared to similar maps for suspect plants to determine if the latter have a common parentage with the subject plant. Map comparisons would involve hybridizations, RFLP, PCR, SSR, and sequencing, all of which are conventional techniques.

Likewise, by means of the present invention, agronomic genes can be expressed in transformed plants. More particularly, plants can be genetically engineered to express various phenotypes of agronomic interest. Exemplary genes implicated in this regard include, but are not limited to, those categorized below:

1. Genes that Confer Resistance to Pests or Disease and that Encode:

A. Plant disease resistance genes. Plant defenses are often activated by specific interaction between the product of a disease resistance gene (R) in the plant and the product of a corresponding avirulence (Avr) gene in the pathogen. A plant variety can be transformed with one or more cloned resistance genes to engineer plants that are resistant to specific pathogen strains. See, for example, Jones, et al., Science, 266:789 (1994) (cloning of the tomato Cf-9 gene for resistance to Cladosporium fulvum); Martin, et al., Science, 262:1432 (1993) (tomato Pto gene for resistance to Pseudomonas syringae pv. tomato encodes a protein kinase); Mindrinos, et al., Cell, 78:1089 (1994) (Arabidopsis RSP2 gene for resistance to Pseudomonas syringae).

B. A Bacillus thuringiensis protein, a derivative thereof or a synthetic polypeptide modeled thereon. See, for example, Geiser, et al., Gene, 48:109 (1986), who disclose the cloning and nucleotide sequence of a Bt δ-endotoxin gene. Moreover, DNA molecules encoding δ-endotoxin genes can be purchased from American Type Culture Collection, Manassas, Va., for example, under ATCC Accession Nos. 40098, 67136, 31995, and 31998.

C. A lectin. See, for example, Van Damme, et al., Plant Molec. Biol., 24:25 (1994), who disclose the nucleotide sequences of several Clivia miniata mannose-binding lectin genes.

D. A vitamin-binding protein such as avidin. See, PCT Application US 93/06487 which teaches the use of avidin and avidin homologues as larvicides against insect pests.

E. An enzyme inhibitor, for example, a protease or proteinase inhibitor or an amylase inhibitor. See, for example, Abe, et al., J. Biol. Chem., 262:16793 (1987) (nucleotide sequence of rice cysteine proteinase inhibitor); Huub, et al., Plant Molec. Biol., 21:985 (1993) (nucleotide sequence of cDNA encoding tobacco proteinase inhibitor I); Sumitani, et al., Biosci. Biotech. Biochem., 57:1243 (1993) (nucleotide sequence of Streptomyces nitrosporeus α-amylase inhibitor).

F. An insect-specific hormone or pheromone such as an ecdysteroid or juvenile hormone, a variant thereof, a mimetic based thereon, or an antagonist or agonist thereof. See, for example, the disclosure by Hammock, et al., Nature, 344:458 (1990), of baculovirus expression of cloned juvenile hormone esterase, an inactivator of juvenile hormone.

G. An insect-specific peptide or neuropeptide which, upon expression, disrupts the physiology of the affected pest. For example, see the disclosure of Pratt, et al., Biochem. Biophys. Res. Comm., 163:1243 (1989) (an allostatin is identified in Diploptera puntata). See also, U.S. Pat. No. 5,266,317 to Tomalski, et al., which discloses genes encoding insect-specific, paralytic neurotoxins.

H. An insect-specific venom produced in nature by a snake, a wasp, etc. For example, see, Pang, et al., Gene, 116:165 (1992), for disclosure of heterologous expression in plants of a gene coding for a scorpion insectotoxic peptide.

I. An enzyme responsible for a hyperaccumulation of a monoterpene, a sesquiterpene, a steroid, hydroxamic acid, a phenylpropanoid derivative or another non-protein molecule with insecticidal activity.

J. An enzyme involved in the modification, including the post-translational modification, of a biologically active molecule; for example, a glycolytic enzyme, a proteolytic enzyme, a lipolytic enzyme, a nuclease, a cyclase, a transaminase, an esterase, a hydrolase, a phosphatase, a kinase, a phosphorylase, a polymerase, an elastase, a chitinase, and a glucanase, whether natural or synthetic. See, PCT Application WO 93/02197 (Scott, et al.), which discloses the nucleotide sequence of a callase gene. DNA molecules which contain chitinase-encoding sequences can be obtained, for example, from the ATCC under Accession Nos. 39637 and 67152. See also, Kramer, et al., Insect Biochem. Molec. Biol., 23:691 (1993), who teach the nucleotide sequence of a cDNA encoding tobacco hornworm chitinase, and Kawalleck, et al., Plant Molec. Biol., 21:673 (1993), who provide the nucleotide sequence of the parsley ubi4-2 polyubiquitin gene.

K. A molecule that stimulates signal transduction. For example, see the disclosure by Botella, et al., Plant Molec. Biol., 24:757 (1994), of nucleotide sequences for mung bean calmodulin cDNA clones, and Griess, et al., Plant Physiol., 104:1467 (1994), who provide the nucleotide sequence of a maize calmodulin cDNA clone.

L. A hydrophobic moment peptide. See, PCT Application WO 95/16776, which discloses peptide derivatives of tachyplesin which inhibit fungal plant pathogens, and PCT Application WO 95/18855, which teaches synthetic antimicrobial peptides that confer disease resistance.

M. A membrane permease, a channel former or a channel blocker. For example, see the disclosure of Jaynes, et al., Plant Sci., 89:43 (1993), of heterologous expression of a cecropin-β lytic peptide analog to render transgenic tobacco plants resistant to Pseudomonas solanacearum.

N. A viral-invasive protein or a complex toxin derived therefrom. For example, the accumulation of viral coat proteins in transformed plant cells imparts resistance to viral infection and/or disease development effected by the virus from which the coat protein gene is derived, as well as by related viruses. See, Beachy, et al., Ann. Rev. Phytopathol., 28:451 (1990). Coat protein-mediated resistance has been conferred upon transformed plants against alfalfa mosaic virus, cucumber mosaic virus and tobacco streak virus, potato virus X, potato virus Y, tobacco etch virus, tobacco rattle virus, and tobacco mosaic virus. Id.

O. An insect-specific antibody or an immunotoxin derived therefrom. Thus, an antibody targeted to a critical metabolic function in the insect gut would inactivate an affected enzyme, killing the insect.

P. A virus-specific antibody. See, for example, Tavladoraki, et al., Nature, 366:469 (1993), who show that transgenic plants expressing recombinant antibody genes are protected from virus attack.

Q. A developmental-arrestive protein produced in nature by a pathogen or a parasite. Thus, fungal endo-α-1,4-D-polygalacturonases facilitate fungal colonization and plant nutrient release by solubilizing plant cell wall homo-α-1,4-D-galacturonase. See, Lamb, et al., Bio/Technology, 10:1436 (1992).

R. A developmental-arrestive protein produced in nature by a plant. For example, Logemann, et al., Bio/Technology, 10:305 (1992), have shown that transgenic plants expressing the barley ribosome-inactivating gene have an increased resistance to fungal disease.

S. Genes involved in the Systemic Acquired Resistance (SAR) Response and/or the pathogenesis-related genes. Briggs, S., “Plant disease resistance. Grand unification system theory in sight,” Current Biology, 5(2) (1995).

T. Antifungal genes. See, Cornelissen and Melchers, “Strategies for Control of Fungal Diseases with Transgenic plants,” Plant Physiol., 101:709-712 (1993); and Bushnell, et al., “Genetic Engineering of Disease Resistance in Cereal,” Can. J. of Plant Path., 20(2):137-149 (1998).

2. Genes that Confer Resistance to an Herbicide, for Example:

A. An herbicide that inhibits the growing point or meristem, such as an imidazolinone or a sulfonylurea. Exemplary genes in this category code for mutant ALS and AHAS enzyme as described, for example, by Lee, et al., EMBO J., 7:1241 (1988), and Miki, et al., Theor. Appl. Genet., 80:449 (1990), respectively.

B. Glyphosate (resistance conferred by mutant 5-enolpyruvlshikimate-3-phosphate synthase (EPSPS) and aroA genes, respectively) and other phosphono compounds, such as glufosinate (phosphinothricin acetyl transferase (PAT) and Streptomyces hygroscopicus PAT bar genes), and pyridinoxy or phenoxy proprionic acids and cyclohexones (ACCase inhibitor-encoding genes). See, for example, U.S. Pat. No. 4,940,835 to Shah, et al., which discloses the nucleotide sequence of a form of EPSPS which can confer glyphosate resistance. A DNA molecule encoding a mutant aroA gene can be obtained under ATCC Accession No. 39256, and the nucleotide sequence of the mutant gene is disclosed in U.S. Pat. No. 4,769,061 to Comai. European Patent Application No. 0 333 033 to Kumada, et al., and U.S. Pat. No. 4,975,374 to Goodman, et al., disclose nucleotide sequences of glutamine synthetase genes which confer resistance to herbicides, such as L-phosphinothricin. See also, Russel, D. R., et al., Plant Cell Report, 12:3, 165-169 (1993). The nucleotide sequence of a phosphinothricin-acetyl-transferase (PAT) gene is provided in European Application No. 0 242 246 to Leemans, et al. DeGreef, et al., Bio/Technology, 7:61 (1989) describe the production of transgenic plants that express chimeric bar genes coding for phosphinothricin acetyl transferase activity. Exemplary of genes conferring resistance to phenoxy proprionic acids and cyclohexones, such as sethoxydim and haloxyfop, are the Acc1-S1, Acc1-S2, and Acc2-S3 genes described by Marshall, et al., Theor. Appl. Genet., 83:435 (1992).

C. An herbicide that inhibits photosynthesis, such as a triazine (psbA and gs+ genes) and a benzonitrile (nitrilase gene). Przibila, et al., Plant Cell, 3:169 (1991), describe the transformation of Chlamydomonas with plasmids encoding mutant psbA genes. Nucleotide sequences for nitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker and DNA molecules containing these genes are available under ATCC Accession Nos. 53435, 67441, and 67442. Cloning and expression of DNA coding for a glutathione S-transferase is described by Hayes, et al., Biochem. J., 285:173 (1992).

D. Acetohydroxy acid synthase, which has been found to make plants that express this enzyme resistant to multiple types of herbicides, has been introduced into a variety of plants. See, Hattori, et al., “An Acetohydroxy acid synthase mutant reveals a single site involved in multiple herbicide resistance,” Mol. Gen. Genet., 246:419-425 (1995). Other genes that confer tolerance to herbicides include a gene encoding a chimeric protein of rat cytochrome P4507A1 and yeast NADPH-cytochrome P450 oxidoreductase (Shiota, et al., “Herbidcide-resistant Tobacco Plants Expressing the Fused Enzyme between Rat Cytochrome P4501A1 (CYP1A1) and Yeast NADPH-Cytochrome P450 Oxidoreductase,” Plant Physiol., 106:17 (1994)); genes for glutathione reductase and superoxide dismutase (Aono, et al., “Paraquat tolerance of transgenic Nicotiana tabacum with enhanced activities of glutathione reductase and superoxide dismutase,” Plant Cell Physiol., 36:1687 (1995)); and genes for various phosphotransferases (Datta, et al., “Herbicide-resistant Indica rice plants from IRRI breeding line IR72 after PEG-mediated transformation of protoplants,” Plant Mol. Biol., 20:619 (1992).

E. Protoporphyrinogen oxidase (protox) is necessary for the production of chlorophyll, which is necessary for all plant survival. The protox enzyme serves as the target for a variety of herbicidal compounds. These herbicides also inhibit growth of all the different species of plants present, causing their total destruction. The development of plants containing altered protox activity which are resistant to these herbicides are described in U.S. Pat. Nos. 6,288,306, 6,282,837, 5,767,373, and International Publication WO 01/12825.

3. Genes that Confer or Contribute to a Value-Added Trait, Such as:

A. Delayed and attenuated symptoms to Bean Golden Mosaic Geminivirus (BGMV), for example by transforming a plant with antisens genes from the Brazilian BGMV. See, Arago, et al., Molecular Breeding, 4:6, 491-499 (1998).

B. Increased the bean content in Methionine by introducing a transgene coding for a Methionine rich storage albumin (2S-albumin) from the Brazil nut as described in Arago, et al., Genetics and Molecular Biology, 22:3, 445-449 (1999).

Methods for Garden Bean Transformation

Numerous methods for plant transformation have been developed including biological and physical plant transformation protocols. See, for example, Miki, et al., “Procedures for Introducing Foreign DNA into Plants,” in Methods in Plant Molecular Biology and Biotechnology, Glick and Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). In addition, expression vectors and in-vitro culture methods for plant cell or tissue transformation and regeneration of plants are available. See, for example, Gruber, et al., “Vectors for Plant Transformation,” in Methods in Plant Molecular Biology and Biotechnology, Glick and Thompson Eds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation—One method for introducing an expression vector into plants is based on the natural transformation system of Agrobacterium. See, for example, Horsch, et al., Science, 227:1229 (1985); Diant, et al., Molecular Breeding, 3:1, 75-86 (1997). A. tumefaciens and A. rhizogenes are plant pathogenic soil bacteria which genetically transform plant cells. The Ti and Ri plasmids of A. tumefaciens and A. rhizogenes, respectively, carry genes responsible for genetic transformation of the plant. See, for example, Kado, C. I., Crit. Rev. Plant Sci., 10:1 (1991). Descriptions of Agrobacterium vector systems and methods for Agrobacterium-mediated gene transfer are provided by Gruber, et al., supra, Miki, et al., supra, and Moloney, et al., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat. No. 5,591,616 issued Jan. 7, 1997.

B. Direct Gene Transfer—Despite the fact the host range for Agrobacterium-mediated transformation is broad, some cereal or vegetable crop species and gymnosperms have generally been recalcitrant to this mode of gene transfer, even though some success has been achieved in rice and corn. Hiei, et al., The Plant Journal, 6:271-282 (1994) and U.S. Pat. No. 5,591,616 issued Jan. 7, 1997. Several methods of plant transformation, collectively referred to as direct gene transfer, have been developed as an alternative to Agrobacterium-mediated transformation. A generally applicable method of plant transformation is microprojectile-mediated transformation where DNA is carried on the surface of microprojectiles measuring 1 to 4 microns. The expression vector is introduced into plant tissues with a biolistic device that accelerates the microprojectiles to speeds of 300 to 600 m/s which is sufficient to penetrate plant cell walls and membranes. Russell, D. R., et al., Pl. Cell. Rep., 12:165-169 (3 Jan. 1993); Aragao, F. J. L., et al., Plant Mol. Biol., 20:357-359 (2 Oct. 1992); Aragao, Theor. Appl. Genet., 93:142-150 (1996); Kim, J., Minamikawa, T., Plant Science, 117:131-138 (1996); Sanford, et al., Part. Sci. Technol., 5:27 (1987); Sanford, J. C., Trends Biotech., 6:299 (1988); Klein, et al., Bio/Tech., 6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein, et al., Biotechnology, 10:268 (1992).

Another method for physical delivery of DNA to plants is sonication of target cells. Zhang, et al., Bio/Technology, 9:996 (1991). Alternatively, liposome and spheroplast fusion have been used to introduce expression vectors into plants. Deshayes, et al., EMBO J., 4:2731 (1985); Christou, et al., Proc Natl. Acad. Sci. USA, 84:3962 (1987). Direct uptake of DNA into protoplasts using CaCl₂ precipitation, polyvinyl alcohol or poly-L-ornithine have also been reported. Hain, et al., Mol. Gen. Genet., 199:161 (1985) and Draper, et al., Plant Cell Physiol., 23:451 (1982). Electroporation of protoplasts and whole cells and tissues have also been described. Saker, M. and Kuhne, T., Biologia Plantarum, 40(4):507-514 (1997/98); D'Halluin, et al., Plant Cell, 4:1495-1505 (1992); and Spencer, et al., Plant Mol. Biol., 24:51-61 (1994).

Following transformation of garden bean target tissues, expression of the above-described selectable marker genes allows for preferential selection of transformed cells, tissues, and/or plants using regeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used for producing a transgenic variety. The transgenic variety could then be crossed with another (nontransformed or transformed) variety in order to produce a new transgenic variety. Alternatively, a genetic trait that has been engineered into a particular garden bean line using the foregoing transformation techniques could be moved into another line using traditional backcrossing techniques that are well known in the plant breeding arts. For example, a backcrossing approach could be used to move an engineered trait from a public, non-elite variety into an elite variety, or from a variety containing a foreign gene in its genome into a variety or varieties that do not contain that gene. As used herein, “crossing” can refer to a simple X by Y cross or the process of backcrossing depending on the context.

Backcrossing

When the term garden bean plant, cultivar or bean line are used in the context of the present invention, this also includes cultivars where one or more desired traits has been introduced through backcrossing methods, whether such trait is a naturally occurring one or a transgenic one. Backcrossing methods can be used with the present invention to improve or introduce a characteristic into the line. The term “backcrossing” as used herein refers to the repeated crossing of a hybrid progeny back to the recurrent parent, i.e., backcrossing 1, 2, 3, 4, 5, 6, 7, 8, 9, or more times to the recurrent parent. The parental bean plant which contributes the gene for the desired characteristic is termed the nonrecurrent or donor parent. This terminology refers to the fact that the nonrecurrent parent is used one time in the backcross protocol and therefore does not recur. The parental bean plant to which the gene or genes from the nonrecurrent parent are transferred is known as the recurrent parent as it is used for several rounds in the backcrossing protocol.

In a typical backcross protocol, the original cultivar of interest (recurrent parent) is crossed to a second line (nonrecurrent parent) that carries the gene or genes of interest to be transferred. The resulting progeny from this cross are then crossed again to the recurrent parent and the process is repeated until a garden bean plant is obtained wherein essentially all of the desired morphological and physiological characteristics of the recurrent parent are recovered in the converted plant, generally determined at a 5% significance level when grown in the same environmental condition, in addition to the gene or genes transferred from the nonrecurrent parent. It has to be noted that some, one, two, three, or more, self-pollination and growing of population might be included between two successive backcrosses. Indeed, an appropriate selection in the population produced by the self-pollination, i.e., selection for the desired trait and physiological and morphological characteristics of the recurrent parent might be equivalent to one, two, or even three additional backcrosses in a continuous series without rigorous selection, saving time, money, and effort to the breeder. A non-limiting example of such a protocol would be the following: (a) the first generation F₁ produced by the cross of the recurrent parent A by the donor parent B is backcrossed to parent A; (b) selection is practiced for the plants having the desired trait of parent B; (c) selected plants are self-pollinated to produce a population of plants where selection is practiced for the plants having the desired trait of parent B and the physiological and morphological characteristics of parent A; (d) the selected plants are backcrossed one, two, three, four, five, six, seven, eight, nine, or more times to parent A to produce selected backcross progeny plants comprising the desired trait of parent B and the physiological and morphological characteristics of parent A. Step (c) may or may not be repeated and included between the backcrosses of step (d).

The selection of a suitable recurrent parent is an important step for a successful backcrossing procedure. The goal of a backcross protocol is to alter or substitute a single trait or characteristic in the original line. To accomplish this, a gene or genes of the recurrent cultivar is modified or substituted with the desired gene from the nonrecurrent parent, while retaining essentially all of the rest of the desired genetic, and therefore the desired physiological and morphological, constitution of the original line. The choice of the particular nonrecurrent parent will depend on the purpose of the backcross, one of the major purposes is to add some commercially desirable, agronomical important trait to the plant. The exact backcrossing protocol will depend on the characteristic or trait being altered to determine an appropriate testing protocol. Although backcrossing methods are simplified when the characteristic being transferred is a single gene and dominant allele, multiple genes and recessive allele(s) may also be transferred and therefore, backcross breeding is by no means restricted to character(s) governed by one or a few genes. In fact, the number of genes might be less important than the identification of the character(s) in the segregating population. In this instance it may then be necessary to introduce a test of the progeny to determine if the desired characteristic(s) has been successfully transferred. Such tests encompass visual inspection, simple crossing but also follow up of the characteristic(s) through genetically associated markers and molecular assisted breeding tools. For example, selection of progeny containing the transferred trait is done by direct selection, visual inspection for a trait associated with a dominant allele, while the selection of progeny for a trait that is transferred via a recessive allele requires selling the progeny to determine which plant carries the recessive allele(s).

Many single gene traits have been identified that are not regularly selected in the development of a new line but that can be improved by backcrossing techniques. Single gene traits may or may not be transgenic. Examples of these traits include, but are not limited to, herbicide resistance (such as bar or pat genes), resistance for bacterial, fungal, or viral disease (such as gene I used for BCMV resistance), insect resistance, enhanced nutritional quality (such as 2s albumine gene), industrial usage, agronomic qualities (such as the “persistent green gene”), yield stability, and yield enhancement. These genes are generally inherited through the nucleus. Some other single gene traits are described in U.S. Pat. Nos. 5,777,196, 5,948,957, and 5,969,212, the disclosures of which are specifically hereby incorporated by reference.

In 1981, the backcross method of breeding accounted for 17% of the total breeding effort for inbred corn line development in the United States, according to Hallauer, A. R., et al., “Corn Breeding,” Corn and Corn Improvement, No. 18, pp. 463-481 (1988).

The backcross breeding method provides a precise way of improving varieties that excel in a large number of attributes but are deficient in a few characteristics. (Page 150 of the Pr. R. W. Allard's 1960 book, published by John Wiley & Sons, Inc., Principles of Plant Breeding.) The method makes use of a series of backcrosses to the variety to be improved during which the character or the characters in which improvement is sought is maintained by selection. At the end of the backcrossing the gene or genes being transferred unlike all other genes, will be heterozygous. Selfing after the last backcross produces homozygosity for this gene pair(s) and, coupled with selection, will result in a variety with exactly the adaptation, yielding ability, and quality characteristics of the recurrent parent but superior to that parent in the particular characteristic(s) for which the improvement program was undertaken. Therefore, this method provides the plant breeder with a high degree of genetic control of his work.

The backcross method is scientifically exact because the morphological and agricultural features of the improved variety could be described in advance and because the same variety could, if it were desired, be bred a second time by retracing the same steps (Briggs, “Breeding wheats resistant to bunt by the backcross method,” Jour. Amer. Soc. Agron., 22:289-244 (1930)).

Backcrossing is a powerful mechanism for achieving homozygosity and any population obtained by backcrossing must rapidly converge on the genotype of the recurrent parent. When backcrossing is made the basis of a plant breeding program, the genotype of the recurrent parent will be modified only with regards to genes being transferred, which are maintained in the population by selection.

Successful backcrosses are, for example, the transfer of stem rust resistance from ‘Hope’ wheat to ‘Bart’ wheat and even pursuing the backcrosses with the transfer of bunt resistance to create ‘Bart 38,’ having both resistances. Also highlighted by Allard is the successful transfer of mildew, leaf spot, and wilt resistances in ‘California Common’ alfalfa to create ‘Caliverde.’ This new ‘Caliverde’ variety produced through the backcross process is indistinguishable from ‘California Common’ except for its resistance to the three named diseases.

One of the advantages of the backcross method is that the breeding program can be carried out in almost every environment that will allow the development of the character being transferred.

The backcross technique is not only desirable when breeding for disease resistance but also for the adjustment of morphological characters, color characteristics, and simply inherited quantitative characters such as earliness, plant height, and seed size and shape. In this regard, a medium grain type variety, ‘Calady,’ has been produced by Jones and Davis. As dealing with quantitative characteristics, they selected the donor parent with the view of sacrificing some of the intensity of the character for which it was chosen, i.e., grain size. ‘Lady Wright,’ a long grain variety, was used as the donor parent and ‘Coloro,’ a short grain variety, as the recurrent parent. After four backcrosses, the medium grain type variety ‘Calady’ was produced.
